Here is a chart of the doubles 00 thur 44.  This is a list of the doubles that haven't been drawn in the longest time.  (2012 or earlier.)  The chart includes the 'sum' of each double.   The Date is coded.  D-12 is December of 2012.  This chart lists the doubles that have never been drawn.  The greyed out numbers have been drawn since I started this chart in Sept of 2015.  (S-15 is Sept of 2015.) 

The sums are color coded.  Blue is low sums.  Green is average sum.  Yellow is high sum.  There are 94 boxed numbers on my list out of a possible 360 boxed doubles.
